Structure-preserving schemes conserving entropy and kinetic energy
Kunal Bahuguna, Ramesh Kolluru, S. V. Raghurama Rao
This paper presents a novel structure-preserving scheme for Euler equations, focusing on the numerical conservation of entropy and kinetic energy. Explicit flux functions engineere…
A kinetic scheme with variable velocities and relative entropy
Shashi Shekhar Roy, S. V. Raghurama Rao
A new kinetic model is proposed where the equilibrium distribution with bounded support has a range of velocities about two average velocities in 1D. In 2D, the equilibrium distrib…
An upwind lattice Boltzmann scheme
Megala A, S. V. Raghurama Rao
A lattice Boltzmann scheme that is close to pure upwind, low diffusive and entropy satisfying Engquist-Osher scheme has been formulated for hyperbolic scalar conservation laws. A m…
A Kinetic Flux Difference Splitting Method for Compressible Flows
Shrinath. K. S, Maruthi. N. H, S. V. Raghurama Rao +1
A low diffusive flux difference splitting based kinetic scheme is developed based on a discrete velocity Boltzmann equation, with a novel three velocity model. While two discrete v…
A stability property for a mono-dimensional three velocities scheme with relative velocity
François Dubois, Benjamin Graille, S. V. Raghurama Rao
In this contribution, we study a stability notion for a fundamental linear one-dimensional lattice Boltzmann scheme, this notion being related to the maximum principle. We seek to…
A Boltzmann scheme with physically relevant discrete velocities for Euler equations
N. Venkata Raghavendra, S. V. Raghurama Rao
Kinetic or Boltzmann schemes are interesting alternatives to the macroscopic numerical methods for solving the hyperbolic conservation laws of gas dynamics. They utilize the partic…
A Lattice Boltzmann Relaxation Scheme for Inviscid Compressible Flows
S. V. Raghurama Rao, Rohan Deshmukh, Sourabh Kotnala
A novel Lattice Boltzmann Method applicable to compressible fluid flows is developed. This method is based on replacing the governing equations by a relaxation system and the inter…
